Underdrive Pulleys

[Guest]

I will be closing the group buy soon, sorry to all those who have missed out, and thanks to the guys who jumped in.

There is a clown on this Forum call Turbotrana and this joke would like to see the back of this group buy + Im not into being cut into by people who have no idea what their on about.

Together we have saved over $2000 and the company making the product is very happy with my work and with the sales. I have replied to to about 150 personal PM's and I'm getting over it.

This wasn't ment to go so long anyway as its dragged on its become far more work than I wanted. So I'll give it another week and that'll be it.

Thanks again, wouldn't mind having another go at it some time but theres members here with small brains who don't like thing they don't understand.

Thanks, NOSXR.

Got you covered 100% mate no worries.

I can understand why the engine would rev out faster, but am not sure where the power gain comes from. Is it simply because everything that the belt is driving is running 20% slower?

9 rwkw is an awesome result - anyone else had their car dynoed?

Underdrive pullies have been available on the V8s for years with great success. They've only recently been available on the BA/BF sixes. I know of a few guys with N/A sixes who've fitted them with, all with mixed sentiments.

From what I've heard, they provide around about a 6rwkw gain on the sixes. But the real point of them is not the extra power provided, but the way they make the engine rev quicker. I would have thought that this alone would be well worthwhile for the Ts to get them on boost quicker.

I don't know about reliability. I know they've caused a few problems on the BOSS V8s with oil pump gears failing. From what I've read the sixes aren't immune to oil pump failures either. And with the sixes having an even longer crank than the 8s, I would say internal engine balancing of this engine would be vital and also tempremental.

Anyway, I'm just looking for opinions of this mod whether it's worth it for the money, whether it would cause any reliability issues, and if anyone has them, what you throughts/sentiments are.

I'm guessing no one has fitted them then? A few of the N/A guys have, with mixed sentiments, but all agree it made some improvement. I will be looking at getting them for my N/A 6 very soon. Would have been nice to have heard about results/opinions of them on the Turbos though.

The manufacturers don't recommend them for the power levels most modded T's are making. There isnt really much point chasing 10 to 15 rwkw for a car thats so easy to get big hp out of...
